OUTLINE: Patients receive filgrastim (G-CSF) subcutaneously (SC) once daily on days 1-6 or 1-7. Patients undergo apheresis on days 6 and 7 or 6-8 to obtain peripheral blood mononuclear cells (PBMC). PBMC are processed for CD34+ cell isolation. These autologous CD34+ hematopoietic progenitor cells are cultured to generate dendritic cells (DC). DC are then pulsed with endotoxin-free keyhole limpet hemocyanin and HLA-A2-01 restricted flu-matrix peptides derived from melanoma-associated tumor antigens (MART-1:27-35, gp100:209-217, and MAGE-3). Antigen-pulsed DC are incubated with interferon alfa to induce DC maturation.
